LevelSequenceActor transform offset for Sequencer lost on value changed

Toggling Lock, Pin, Ignore on subsequences or adding new transform key on a character inside a subsequence the Actors lose the LevelSequenceActor transform offset they have at preview and go back to world origin, playback is based on the origin instead of LevelSequenceActor after this.

If I scrub back to frame -1 and move to a frame > 0 the playback is correct again, relative to LevelSequenceActor.

Simple repro (possibly the same issue, but possibly not):

1. Create a new level sequence
2. Add a static mesh to the level sequence and key the transform with different values at different times
3. Select the level sequence actor, override instance data, set the transform origin to 0, 100, 0

EXPECTED: The cube should move up 100 units.

ACTUAL: The cube doesn't move up 100 units. If you scrub, it does re-evaluate and move up 100 units.

 

 

Steps to Reproduce

I've got a LevelSequence with:

• MasterSequence

• Characters

• Area1
• Area2

Toggling Lock, Pin, Ignore on "Characters", "Area1" or "Area2" subsequences or adding new transform key on a character inside "Area1".

This is not a 100% repro, I'm not sure what are the exact reasons this is happening as it's not reproducible in all LevelSequences.
